CIFZCATION forming part of Letters Patent No. 339,891, dateci April 13, 1886.

A pplicniion filed November 28, 1585. Serial X0. Il /i171. (Yo moth-l.)

Yo r17 whom may concern Be it known that I, GABRIEL I. B. Hora, of Jamaica, Queens county, State of New York, have invented a new and useful Improvement in ijyclometcrs, of which the following" is specification.

The iyclometers now in use on bicycles and principally, in combining a cyclometcr with a cranlcpin of a bicycle or similar vehicle.

My invention also consists of a cycloineter constructed to receive positive, intermittent, or stop motion from a point, projection, or cogwvhecl arranged to revolve with the crank or other part of the bicycle.

Reference is to he had to the accompanying drawings, forming a part of this spec; fication, in which similar letters of reference indicate GOI'IQSIJOElLilllf parts in all the figures.

Figure in is a front elevation ol a pedal and crankpin of a bicycle having my new cyclom" eter 111; (l thereto, a part of the face or dial of the L) clometcr broken away to show the construction of the reg gtering mechanism, Fig. 2 is find elevation of the same. Fig. 8 is aside elevation of a part of 2x biogole, showing the crank-pin and pedal with cyclometer attached in position for use:

A represents the crank-pin of abicycle, arlaptctl to he rigidly secured to a crank, 13, of the bicycle, so as to revolve therewith, and making one revolution for every revolution of the wheel RV To the cranlrpin A. is attached the cycloneeter C, ant:v above the cyclometer is applied to the crank-pin the pedal D, that turns loosely upon the in the ordinary w Bi secured to the crank-pin A is the device te E, for operating the cyclonieter or registelutions o device, for registering the revoic wheel V? or the distance covered.

The cyclometcr consists, essentially notched operating-"plate, a, a wornrsh and registering mechanism 0, th in and registering mechanism being" nclose a suitable casing, (Z, provided with end flanges, d", for attaching the eycloineter to the pe laispindles J; k, and provided also wi 'h a ilial, c, before which the pointers ,7" move, anrl on which are marked graduations ll'lllltfiillllg listanccs in miles and parts of miles.

The plate E on the crank-pin is, hy preferonce, for the most part made circular with the single peripheral projection or point 5;. The plate a on the worm-shaft z) is, by prcterence, formed with several equidistant notches it, into which the point 5 is adapted to strike as the plate E and crank-pin A revolve for impart in an intermittent rotary motion to the plate registering mechanism u, woriawheel I), 31111 c, and hands f. Between the notches 13:- the plate I is formed at its edge with the concavcs i, each forming an arc of a circle having the same radius the circle described by the cular portion of the disk E. The object ol' this is so that the tlisk 13 will accurately fit in the concaves i and act as a stop to the plate a and other mechanism of the Uf,(:l0ii1l%i0l, and pre vent them from revolving in either direction, except while the point ,7 is in contact with the plate a. The plate E is cut awny at each of the point g, as shown at gg', Fig. 2, to p e" vent binding of the plates h; a at the time we point 9 passes the notches anti operates the plate a.

The cog-wheel c imparts motion directly to the long hantlf, while the short hand is l a slow motion equal to one-tenth the see the long hand by means of an ordinary t. of clockgearing. (Shown in full and (lottetl lines in Fig. 1.)

Having thus fully described my 'I I claim as new and desire to secure by Letters Patent-- 1, The combination, with the cranl pin and the pedal of bicycle or similar vehicle, of a eyclonieter, 0, attached to the pedal, and. means, substantially as described, for operating the cyclometer, as and for the nnrposes set forth,

2. The crank-pin oi" bicycle or similar vehicle, having an operating plate or device, 1 biuation with the notched and curved plate a, [o E, rigidly secured thereto, in combination the worm-shaft b, and the gear mechanism of with registering mechanism attached to the the cyclometer, the plate a being held in close pedal and an intermediate plate or device for contact with the toothed plate E on the crank- 5 causing the plate E to operate the registering pin, substantially as described.
